Dear Sir,
Unfortunately I was shooting in dusty weather and discovered rough noise while winding and and zooming but with blowing around this sound has gone BUT i can see one piece of sand at the lens of course from inside the element which is sticking from inside so far it does not affect as far i can notice on the lens performance but still need to know what to do to get the lens clean and to get rid of this sand.
